She is in a large and it's a good fit around the legs. I probably could take the waist to it's smallest (ie join the front tabs) but I think that would be too tight on the legs then.
I do have a cover that I'm using with a Mandy Mac PN and they work fine so I might give that a go. Though it's a fleece cover and probably not firm enough fitting to keep wings in place I don't think. I can't use wool on her. Can only try I guess - thankyou.
